  Although not shown, the dry air supply means 50 shown in FIG. 1 has the same configuration as the cleaning water supply means 20 with respect to the fluid supply pipe, the fixed connection portion, and the support piece, and the fixed connection portion. The only difference is that the air supply source is connected to.

  Below, the operation | movement which cuts and wash | cleans a workpiece in the cutting device 1 is demonstrated. The diameter of the first workpiece W1 shown in FIG. 1 has a first size (for example, φ300 mm). The first workpiece W1 has a device D in each region of the surface partitioned by a plurality of intersecting streets S. When the first workpiece W1 is cut, the first workpiece W1 is integrated with the annular frame F via the protective tape T as shown in FIG. Contained.

  The carry-in / out means 4 shown in FIG. 1 draws the first workpiece W1 integrated with the frame F through the protective tape T from the cassette 3 and temporarily places it in the temporary placement area 5. Next, the transport means 8 transports the first workpiece W1 temporarily placed in the temporary placement area 5 to the holding means 6 that stands by in the carry-in / out area P1. After the workpiece W <b> 1 is held by the holding means 6, the annular frame F is clamped by the clamp portion 7.

  Next, the holding means 6 is moved toward the cutting area P2 by the cutting feed means 11. When the holding means 6 moves below the cutting means 12 located in the cutting region P2, the first workpiece W1 is cut along the street S by the rotating cutting blade 14. During the cutting, cutting water is supplied to the contact portion between the cutting blade 14 and the first workpiece W1.

  After the first workpiece W1 is cut, the holding means 6 is moved from the cutting area P2 toward the loading / unloading area P1 by the cutting feed means 11 in order to remove the contamination adhered to the first workpiece W1. Then, cleaning is performed by supplying cleaning water from the fluid supply pipe 21 toward the first workpiece W1 while passing the holding unit 6 below the cleaning water supply unit 20.

  Specifically, the knob portion 29 formed at one end of the cleaning water supply pipe 21 shown in FIG. 2 is rotated to direct the cleaning water supply pipe 21 in the first direction 40 shown in FIG. Here, the first direction 40 allows the supply hole 31 and the first flow path 25 shown in FIG. 5 to communicate with each other, and the first fluid supply hole 27 is directed downward as shown in FIG. The cleaning water 9 introduced into the first flow path 25 through the supply hole 31 is directed from the first fluid supply hole 27 to the first workpiece W1. It refers to a direction that regulates the ejection of cleaning water 9 from the second fluid supply hole 28 toward the first workpiece W1 while ejecting toward W1.

  In the state where the fluid supply pipe 21 is oriented in the first direction 40, as shown in FIG. 6B, the first fluid supply holes 27 on both ends in the Y-axis direction are the outer peripheral portions Wc of the first workpiece W1. It is positioned on the extension line of the tangent line in the X-axis direction. That is, the first fluid supply hole 27 does not exist outside the space between the two tangents in the X-axis direction of the outer peripheral portion Wc. In this way, the length between the first fluid supply holes 27 at both ends can be made to substantially match the diameter of the first workpiece W1 simply by rotating the fluid supply pipe 21, and the cleaning water supply The pipe 21 does not supply excessive fluid from the first fluid supply hole 27 to the outer peripheral side of the first workpiece W1.

  In this way, with the fluid supply pipe 21 oriented in the first direction, the holding means 6 holding the first workpiece W1 is moved in the X-axis direction to approach the cleaning water supply means 20, and FIG. As shown in FIG. 5, when the holding unit 6 moves in the X-axis direction and passes below the cleaning water supply pipe 21, the cleaning water 9 that has flowed into the first flow path 25 by the cleaning water supply unit 20 is removed. By supplying the first fluid supply hole 27 toward the upper surface of the first workpiece W1, contamination attached to the device D is removed.

  When the holding means 6 is further moved in the X-axis direction while cleaning the first workpiece W1 held by the holding means 6, the dry air supply means 50 has the same structure as the cleaning water supply pipe 21. Dry air 59 is supplied from the first fluid supply hole 57 of the dry air supply pipe 51 to the upper surface of the first workpiece W1. Thereby, the cutting water and cleaning water remaining in the device D are removed. In this way, the cleaning and drying of the first workpiece W1 after cutting is completed.

  When the second workpiece W2 having a second size (for example, φ450 mm) larger than the diameter of the first workpiece W1 is cleaned, it is formed at one end of the cleaning water supply pipe 21 shown in FIG. The knob portion 29 is rotated so that the cleaning water supply pipe 21 is directed in the second direction 41 shown in FIG. Here, the second direction 41 allows the supply hole 31 and the second flow path 26 shown in FIG. 5 to communicate with each other, and the second fluid supply hole 28 is directed downward as shown in FIG. The cleaning water 9 introduced into the second flow path 26 through the supply hole 31 is directed from the second fluid supply hole 28 toward the work piece in a direction that is positioned so as to face the second work piece W2. And the direction in which the cleaning water 9 is restricted from being ejected from the first fluid supply hole 27 toward the workpiece.

  In the state where the cleaning water supply pipe 21 is oriented in the second direction 41, as shown in FIG. 8 (b), the second fluid supply holes 28 on both ends in the Y-axis direction are the outer peripheral portions of the second workpiece W2. The second fluid supply hole 28 does not exist outside the space between the two tangents of Wc in the X-axis direction.

  In this state, as in the cleaning operation of the first workpiece W1 shown in FIG. 7, the cleaning water 9 is supplied from the second fluid supply hole 28 to the upper surface of the second workpiece W2 by the cleaning water supply means 20. The supplied contaminants attached to the device D are removed. In this way, the length between the second fluid supply holes 28 at both ends can be made to substantially match the diameter of the first workpiece W1 simply by rotating the fluid supply pipe 21, so that a large workpiece It is possible to perform sufficient cleaning corresponding to the workpiece.

  Next, while cleaning the second workpiece W1 held by the holding means 6a that holds the workpiece, the holding means 6a further moves in the X-axis direction, and the first workpiece W1 shown in FIG. Similarly to the drying operation, the second workpiece W2 is dried by the dry air supply means 50. That is, after the dry air supply pipe 51 is rotated and the second fluid supply hole 58 is directed downward, the dry air supply means 50 dries from the second fluid supply hole 58 toward the upper surface of the second workpiece W2. Air is supplied, and the cutting water and cleaning water remaining in the device D are removed. In this way, the cleaning and drying of the second workpiece W2 after cutting is completed.

As described above, when the first workpiece W <b> 1 is cleaned by the cleaning water supply means 20, the cleaning fluid supply pipe 21 is directed in the first direction 40 to configure the first fluid supply unit 22. It is possible to restrict the washing water 9 from being ejected from the first fluid supply hole 27 and from the second fluid supply hole 28 constituting the second fluid supply part 23. Further, when the second workpiece W2 is cleaned, the cleaning water 9 is jetted from the plurality of second fluid supply holes 28 by directing the cleaning water supply pipe 21 in the second direction 41 and the first fluid. It is possible to restrict the washing water 9 from being ejected from the supply hole 27.
Accordingly, since it is possible to change the ejection width of the cleaning water in accordance with the size of the workpiece, there is no possibility of supplying the cleaning water 9 excessively to the outer peripheral side of the small-size workpiece. As a result, it is possible to reduce the supply amount of water and to eject sufficient cleaning water within a necessary range for a large-sized workpiece.

  The means for cleaning workpieces of different sizes is not limited to the structure of the cleaning water supply means 20 described above. As a second example of the means for cleaning workpieces of different sizes, there is a cleaning water supply means 60 shown in FIG. The cleaning water supply means 60 includes a cylindrical cleaning water supply pipe 61 that can rotate around a central axis. The cleaning water supply pipe 61 includes a plurality of first fluid supply holes 62 and a cleaning water supply. A plurality of second fluid supply holes 63 that are symmetrical with respect to the rotation center of the pipe 61 and a flow path 64 that communicates with the first fluid supply hole 62 and the second fluid supply hole 63 are formed. Similar to the cleaning water supply pipe 21 of the cleaning water supply means 20, the number of the second fluid supply holes 63 is different from the number of the first fluid supply holes 62.

  As shown in FIGS. 9 and 10, on the outer peripheral side of the cleaning water supply pipe 61, a restriction cover 65 that selectively closes the first fluid supply hole 62 or the second fluid supply hole 63 to restrict the ejection of fluid. It has. As shown in FIG. 10, a knob portion 66 is formed at one end of the cleaning water supply pipe 61, and when the knob portion 66 is turned, the regulation cover 65 rotates and the first fluid supply hole 62 or the second fluid supply is supplied. The hole 63 can be selectively closed. Therefore, the cleaning water supply means 60 can also change the supply amount of the cleaning water in accordance with the size of the workpiece, and the supply amount of the cleaning water can be reduced.

  In the example shown in FIGS. 1 to 10, the fluid supply pipe is configured to correspond to the size of two types of workpieces. However, the size of the fluid supply pipe is 3 by providing three or more types of fluid supply units. More than one type of workpiece can be handled. For example, the configuration shown in FIG. 4 is changed so that the interior of the fluid supply pipe is divided into three or more, and only one of the three partitioned spaces communicates with the fluid supply path 31 shown in FIG. To. Further, the configuration shown in FIG. 9 is changed so that the restriction cover 65 closes two of the three or more types of fluid supply units.
